Hello Svein,
I created the original fuel flow SM12209 Modification and asked Ian Rickard to
get it 'passed' for use on my TriGear, through the LAA.
I also have a 912S and have been using this MOD since early 2009 - my a/c has
completed
about 150hrs with it fitted - including about 35hr around France and
Italy on one of the Europa Club trips. I have a single FloScan 201A sensor and
a Stratomaster Infinity readout unit combination installed.
Over the time of its use I have calibrated it by adjusting the readout units K
factor and conclude that it is accurate within about a 5% error. I agree that
the flow rates change with engine speed but propose that the average accuracy
is quite good enough to keep track of useage and cross-correlate with my two
other forms of fuel quantity monitoring, a capacitance fuel probe and the
sight-glass
tube arrangement - though the latter does not seem to be very useful in
the air due to ram-effect air pushing down the fuel level in the tube.
I've fitted my sensor in the ine bwtween the electric boost pump outlet and the
mechanical pump inlet.
Clive. :)
